*Important: Students may stay after school until 2:45 any day during the current grade term in order to finish a lab. Once grades close for the term, labs cannot be made up. To calculate grade point average: Classwork/labs = 45% Tests= 30% Quizzes=20% Homework= 5% Students have a week to correct quizzes and tests to receive 50% credit for points lost. Homework is due the following day unless noted. Late homework will be accepted with a 10% deduction per late day.
